AMy invention relates to improvements inmatrix audimat headsor ltype casting macliines and the like and hasifor one object to provide animproved type of matrix 5. 'wherein a pivotedor*articulated locking and matrixipropellinghead may be associated with the matrix stripivithout increasing the eiective thicknessof the matrix strip and Without sacriiice in 'strength or rigidity.

Another object is .to provide 1a new vand im-V proved forni of matrix strip. Other oh. jects @Willappear tem-time t0 tmefthro'ushr out the sperciiication'and claims.

I have shown my invention as applied to a' matrix strip and so referred to it in the speciication-eand claims for purposes of convenience. It will, ofcourse, be obvious that'the same invention might be applied toa .print-- ing strip in which case instead of having the impression forming elements at the bottom of the pockets A1, the pockets would become diriding pockets between the wallsD kand in this case the walls D would carryrprinting characters D1 as shown 1n Figure 7. Y It-will be understood therefore that in my claims where I reter to a matrix strip for type cast-l ing machines the language is used for purposes 1. A matrix for type casting l machines and the like comprising a strip Ahaving a plurality.' of spaced recesses in one edge thereof, partition walls dividing said recesses, impression forming elements in the bottoms of said vrecesses, the opposed ends of the strips beyondA the recessed area projecting downwardly beyond the partition walls, vand a matrix 'bed upon which such strips travelwithjthe down'- wardly projecting elements engaging such bed, the partition walls being heldabove it.

2.
